Definitions
- the present invention relates to a vibration damping apparatus, reaction force processing system, a stage apparatus, an exposure apparatus, a substrate processing device, and a method for manufacturing an article.
- An exposure apparatus includes a stage (wafer stage or reticle stage) for moving and positioning a wafer or reticle at a high speed, but in driving the stage, a reaction force of an inertial force caused by acceleration or deceleration is transmitted to a platen and shakes or vibrates the platen or floor.

- FIG. 6 is a configuration diagram of an exposure apparatus that includes the vibration damping apparatus according to each embodiment.
- FIG. 1A is a sectional view of the vibration damping apparatus 100 according to this embodiment.
- FIG. 1B is a sectional view taken along a line A-A in FIG. 1A , and viewed from a vertical direction (Z-axis direction in FIG. 1A ).
- a base 101 is fastened to a vibrating target member (target member) to be damped.
- a damping member 102 is attached to the base 101 .
- a support member 104 is provided to the damping member 102 on the side of the damping member 102 opposite to the base 101 .
- Amass body 106 is provided to the other end of the support member 104 (on the side of the support member 104 opposite to the damping member 102 ).
- a housing 103 is fastened to the base 101 .
- One end of an elastic member 105 such as a diaphragm or a bellofram is attached to the one end of the support member 104 on the side of damping member 102 .
- the other end of the elastic member 105 is attached to the housing 103 .
- a hole 109 is formed in the housing 103 , and an inlet port 107 for sucking compressed air is provided in a space 110 formed by the elastic member 105 and the housing 103 .
- a piping member 108 is inserted into the inlet port 107 , and compressed air whose pressure is controlled is suppliable to the space 110 formed by the elastic member 105 and the housing 103 .
- the elastic member 105 connects the housing 103 and the support member 104 to each other, and its rigidity changes according to the pressure of the compressed air.
- the support member 104 is disposed between the elastic member 105 and the mass body 106 in the vertical direction, and restricted from moving in the vertical direction by the damping member 102 .
- a circular hole 111 is formed in the housing 103 .
- the support member 104 has a cylindrical shape disposed inside the hole 111 (or circular section when viewed from the vertical direction). This structure can prevent the effect of the vibration damping apparatus 100 from having anisotropy.
- FIGS. 2A and 2B a description will be given of the operation of the vibration damping apparatus 100 .
- FIGS. 2A and 2B explain the vibration damping apparatus 100
- FIG. 2A illustrates a case where the support member 104 is located at the center
- FIG. 2B illustrates a case where the support member 104 is located off the center.
- the elastic member 105 has an automatic centripetal action. As illustrated in FIG. 2A , in the case where the support member 104 is located at the center, the elastic member 105 contacts the support member 104 uniformly (so that the depth of the groove formed by the elastic member 105 is constant). On the other hand, as illustrated in FIG. 2B , in the case where the mass body 106 and the support member 104 vibrate, the depth of the groove formed by the elastic member 105 becomes deeper as the width becomes narrower and shallower as the width becomes wider. At this time, a restoring force acts in a direction from the narrow side to the wide side of the groove, and the support member 104 is returned to the center position (centerline C). Since the magnitude of this restoring force is proportional to the pressure of the supplied gas (compressed air) and an eccentricity amount of the support member 104 , the rigidity of the vibration damping apparatus 100 can be controlled by controlling the pressure of the supplied gas.
- the natural frequency of the vibration damping apparatus 100 is determined based on the mass body 106 and the rigidity. Therefore, the natural frequency of the vibration damping apparatus 100 can be controlled by controlling the rigidity. This configuration can reduce the vibration of the target by causing the mass body 106 to absorb the vibration of the target and vibrate instead.

Description
- The present invention relates to a vibration damping apparatus, reaction force processing system, a stage apparatus, an exposure apparatus, a substrate processing device, and a method for manufacturing an article.
- An exposure apparatus includes a stage (wafer stage or reticle stage) for moving and positioning a wafer or reticle at a high speed, but in driving the stage, a reaction force of an inertial force caused by acceleration or deceleration is transmitted to a platen and shakes or vibrates the platen or floor. Japanese Patent Laid-Open No. (“JP”) 5-121294 discloses a photolithography apparatus (reaction force processing system) that generates a compensation force having the same magnitude as that of a generated reaction force in a direction opposite to a direction of the generated reaction force.
- There is known a dynamic vibration absorber or dynamic damper that has a spring and a mass body whose natural frequency is the same as a frequency in question, wherein the mass body absorbs vibration of a target and vibrates instead, thereby reducing the vibration of the target. However, in a case where there are a plurality of frequencies in question, the vibration of the target cannot be reduced. Accordingly, JP 2017-133639 discloses a vibration damping apparatus that makes the natural frequency variable using a magnetic elastomer.
- In the photolithography apparatus disclosed in JP 5-121294, in the case where the natural frequency of the apparatus that generates the compensation force and the frequency of the compensation force are close to each other, the vibration may increase and deteriorate the performance of the photolithography apparatus. The vibration damping apparatus disclosed in JP 2017-133639 changes the rigidity of rubber by controlling an intensity of a magnetic field, and thus is not applicable to a structure (an actuator using the magnetic force) that generates a magnetic flux such as a linear motor.
- The present invention provides a vibration damping apparatus, a reaction force processing system, a stage apparatus, an exposure apparatus, a substrate processing device, and a method for manufacturing an article, each of which can support an actuator that utilizes a magnetic force.
- A vibration damping apparatus according to one aspect of the present invention is configured to damp a vibration of a target member and includes a mass body, a base disposed on the target member, a support member disposed on the base and configured to support the mass body, a housing disposed on the base so as to surround the support member, an elastic member disposed so as to form a space in the housing and configured to apply a force to the support member, and a control unit configured to control a pressure of a fluid in the space by supplying the fluid to the space based on a vibration state of the target member.
- A reaction force processing system according to another aspect of the present invention includes the above vibration damping apparatus, a coil, and a magnet. A stage apparatus according to another aspect of the present invention includes a stage and the above vibration damping apparatus. An exposure apparatus according to another aspect of the present invention includes a projection optical system, and the above vibration damping apparatus. A substrate processing apparatus for processing a substrate includes a stage configured to hold the substrate, and the above vibration damping apparatus configured to damp a vibration of the stage. A manufacturing method of an article according to another aspect of the present invention includes the steps of processing a substrate using the above substrate processing apparatus, and manufacturing the article from a processed substrate.

- Referring now to
FIGS. 1A and 1B , a description will be given of a configuration of a vibration damping apparatus (variable-rigidity vibration damping apparatus) 100 according to a first embodiment of the present invention.FIG. 1A is a sectional view of thevibration damping apparatus 100 according to this embodiment.FIG. 1B is a sectional view taken along a line A-A inFIG. 1A , and viewed from a vertical direction (Z-axis direction inFIG. 1A ). - In the
vibration damping apparatus 100, abase 101 is fastened to a vibrating target member (target member) to be damped. Adamping member 102 is attached to thebase 101. Asupport member 104 is provided to thedamping member 102 on the side of thedamping member 102 opposite to thebase 101. Amassbody 106 is provided to the other end of the support member 104 (on the side of thesupport member 104 opposite to the damping member 102). Ahousing 103 is fastened to thebase 101. One end of anelastic member 105 such as a diaphragm or a bellofram is attached to the one end of thesupport member 104 on the side ofdamping member 102. The other end of theelastic member 105 is attached to thehousing 103. Ahole 109 is formed in thehousing 103, and aninlet port 107 for sucking compressed air is provided in aspace 110 formed by theelastic member 105 and thehousing 103. Apiping member 108 is inserted into theinlet port 107, and compressed air whose pressure is controlled is suppliable to thespace 110 formed by theelastic member 105 and thehousing 103. - In this embodiment, the
elastic member 105 connects thehousing 103 and thesupport member 104 to each other, and its rigidity changes according to the pressure of the compressed air. Thesupport member 104 is disposed between theelastic member 105 and themass body 106 in the vertical direction, and restricted from moving in the vertical direction by thedamping member 102. - As illustrated in
FIG. 1B , acircular hole 111 is formed in thehousing 103. Thesupport member 104 has a cylindrical shape disposed inside the hole 111 (or circular section when viewed from the vertical direction). This structure can prevent the effect of thevibration damping apparatus 100 from having anisotropy. - Referring now to
FIGS. 2A and 2B , a description will be given of the operation of thevibration damping apparatus 100.FIGS. 2A and 2B explain thevibration damping apparatus 100,FIG. 2A illustrates a case where thesupport member 104 is located at the center, andFIG. 2B illustrates a case where thesupport member 104 is located off the center. - It is known that the
elastic member 105 has an automatic centripetal action. As illustrated inFIG. 2A , in the case where thesupport member 104 is located at the center, theelastic member 105 contacts thesupport member 104 uniformly (so that the depth of the groove formed by theelastic member 105 is constant). On the other hand, as illustrated inFIG. 2B , in the case where themass body 106 and thesupport member 104 vibrate, the depth of the groove formed by theelastic member 105 becomes deeper as the width becomes narrower and shallower as the width becomes wider. At this time, a restoring force acts in a direction from the narrow side to the wide side of the groove, and thesupport member 104 is returned to the center position (centerline C). Since the magnitude of this restoring force is proportional to the pressure of the supplied gas (compressed air) and an eccentricity amount of thesupport member 104, the rigidity of thevibration damping apparatus 100 can be controlled by controlling the pressure of the supplied gas. - The natural frequency of the
vibration damping apparatus 100 is determined based on themass body 106 and the rigidity. Therefore, the natural frequency of thevibration damping apparatus 100 can be controlled by controlling the rigidity. This configuration can reduce the vibration of the target by causing themass body 106 to absorb the vibration of the target and vibrate instead. - Referring now to
FIGS. 3A and 3B , a description will be given of a reactionforce processing system 310 that includes thevibration damping apparatus 100 according to this embodiment.FIG. 3A is a structural view of anexposure apparatus 300 provided with the reactionforce processing system 310.FIG. 3B is a detailed view of the reactionforce processing system 310. - In the
exposure apparatus 300, a projectionoptical system 301 is mounted on atop frame 302. Thetop frame 302 is connected to abottom frame 304 via apillar member 303. Aplaten 401 provided with a traveling surface of thestage apparatus 400 is mounted on thebottom frame 304. Thestage apparatus 400 is mounted movably on the traveling surface. - A chuck (not shown) provided on the
stage apparatus 400 holds asubstrate 600 to be exposed. This structure exposes a pattern of an original (not shown) onto a plurality of exposed areas on the substrate via the projectionoptical system 301 while thestage apparatus 400 is stepped. Theexposure apparatus 300 is provided with a vibration isolating table 306 between thebottom frame 304 and the floor so as to prevent external vibration from being transmitted from the floor to thestage apparatus 400. - The reaction
force processing system 310 in theexposure apparatus 300 is attached to a base 305 fixed to the floor, and its other end is fixed to theplaten 401 via a linear motor (thrust generator that generates magnetism) described later. As illustrated inFIG. 3B , in the reactionforce processing system 310, ahousing 311 is fixed to a frame extending from thebase 305, and a coil (not shown) is provided inside thehousing 311. Amagnet 312 is provided on thehousing 311 via a gap. Themagnet 312 is attached to theplaten 401 via theframe 313. Thehousing 311 and themagnet 312 in the linear motor do not mechanically contact each other, and are configured so that the vibration of the floor is not transmitted to thebottom frame 304 via the reactionforce processing system 310. - The reaction
force processing system 310 generates a compensation force that cancels the reaction force generated when thestage apparatus 400 is stepped. This embodiment attaches thehousing 311 provided with a coil to thebase 305 and themagnet 312 to theplaten 401, but the present invention is not limited to this embodiment and may use a reverse configuration. This embodiment attaches the reactionforce processing system 310 to theplaten 401, but may attach it to thebottom frame 304 or thepillar member 303. - In the reaction
force processing system 310, thevibration damping apparatus 100 is disposed on a structure fastened to theplaten 401. The pipingmember 108 is attached to thevibration damping apparatus 100, and connected to acontrol unit 500. Thecontrol unit 500 controls (adjusts) the pressure of the compressed air. - Referring now to
FIG. 4 , a description will be given of thecontrol unit 500 of thevibration damping apparatus 100.FIG. 4 is a block diagram of thecontrol unit 500. Thecontrol unit 500 includes amemory 501, acalculation unit 502, and apressure adjusting unit 503. WhileFIG. 4 illustrates thecontrol unit 500 that is separated from thevibration damping apparatus 100, thecontrol unit 500 may form part of thevibration damping apparatus 100. - The
memory 501 stores a frequency map between a position of thestage apparatus 400 and a compensation force at each position. Thecalculation unit 502 determines the natural frequency (target frequency) of thevibration damping apparatus 100 based on the frequency map stored in thememory 501, and determines the supplied pressure of the compressed air based on the target frequency. - The
pressure adjusting unit 503 controls the pressure of the compressed air, which is supplied into thevibration damping apparatus 100 via theinlet port 107. Thereby, the natural frequency of thevibration damping apparatus 100 can be adjusted to the vibration frequency of the reactionforce processing system 310 of theexposure apparatus 300, and the vibration of the reactionforce processing system 310 can be effectively attenuated. As a result, the vibration of thebottom frame 304 of theexposure apparatus 300 can be suppressed and the exposure performance can be improved. - That is, in this embodiment, the
control unit 500 may control the pressure of the compressed air so as to change the natural frequency of thevibration damping apparatus 100. Thecontrol unit 500 may determine the natural frequency of thevibration damping apparatus 100 based on the frequency of the compensation force that cancels the reaction force, and control the pressure of the compressed air based on the natural frequency. Thecontrol unit 500 may determine the natural frequency of thevibration damping apparatus 100 based on the frequency map of the compensation force stored in thememory 501. - In this embodiment, the fluid supplied to the
vibration damping apparatus 100 is compressed air, but the present invention is not limited to this embodiment, and may supply another fluid such as water and oil via theinlet port 107. In this embodiment, a singlevibration damping apparatus 100 is mounted on a single reactionforce processing system 310, but the present invention is not limited to this embodiment. A plurality ofvibration damping apparatuses 100 may be mounted on a single reaction force processing system. At this time, by changing the frequency of each vibration damping apparatus, the vibration component of each frequency can be reduced. - Referring now to
FIG. 5 , a description will be given of a structure of a vibration damping apparatus (variable-rigidity vibration damping apparatus) 200 according to a second embodiment of the present invention.FIG. 5 is a sectional view of thevibration damping apparatus 200 according to this embodiment. - The

Since the other configuration is similar to that of the first embodiment, a description will be omitted by designating the configuration having the same function by the same reference numeral. - The second
elastic member 209 connects thesupport member 104 and thehousing 103 to each other. This configuration can connect thesupport member 104 and thehousing 103 to each other using not only theelastic member 105 but also the elastic member provided in parallel with theelastic member 105. For example, by forming the secondelastic member 209 with a spring member (spring element) such as a metal leaf spring, reliability such as performance and durability can be improved. - A substrate processing apparatus according to another embodiment of the present invention will be described. This embodiment will describe an exposure apparatus that exposes a substrate to form a pattern on the substrate, as an example of the substrate processing apparatus, but the present invention is not limited to this example. For example, the present invention is also applicable to a substrate processing apparatus such as an imprint apparatus that forms a pattern of an imprint material on a substrate using a mold, and a drawing apparatus that irradiates a substrate with charged particle beams to form a pattern on the substrate. The present invention is also applicable to a substrate processing apparatus such as a coater for applying a photosensitive medium onto a surface of a substrate and a developer for developing the photosensitive medium on which a pattern is transferred. The present invention is also applicable to a substrate processing apparatus such as a film forming apparatus (such as a CVD apparatus), a processing apparatus (such as a laser processing apparatus), an inspection apparatus (such as an overlay inspection apparatus), and a measuring apparatus (such as a mark measuring apparatus).
